That makes sense, I don't remember flying to NJ back in 2012. That was long before I had a laptop program, or these handheld units to send out.

Hi Stuart,

Do you know the boost levels on the V6 and V6 F-Types? I have an XE V6 and don't know if it has the same pulley as the F Type V6 or V6s. I read somewhere that the Xe runs only 11.6 psi on its 340hp TVS R1320 blower.

Id like to get the tune and upper pulley if my stock pulley isn't the same as the 380 F Type, or just do the lower pulley only or even both along with the tune?

 

On the V8 cars they are fitted with a 65mm upper pulley, the 'R' is running 13psi, and the SVR/Project 7 are at 15psi, but the difference is software related not mechanical. I suspect the 495BHP 'S' is running even less boost.

I believe the V6 is in a similar range, except that you already have a 62mm upper pulley. The 340BHP base model is again, just software limited versus the 380BHP 'S' version so if the car is running 11.6psi stock then I believe it can be bumped slightly by controlling the valve.

Either way, our software for your car, bone stock with no other mods will get you to 416BHP and a whole whack more torque without touching the pulleys.

 

With the right pulley combination (and tune), you can get a total of close to 20psi of boost out of the TVS R1320 on the V6.

 

So it is safe to say that the 340hp XE is in no way different than the F- Pace/F-Type V6 mechanically and I can just do the flash alone and bump it 416hp mentioned? And with just the lower pulley added will then bump it to the 453hp claims?

I am hesitant to ever touch the upper pulley when I have the lower pulley on because of the OP post that it over drives the blower by 1k rpms if this is true on the V6 variant?

Or am I wrong and I can safely do both the upper and lower pulley with the tune and still be safe?

 

Yes that is correct, and you should see 416BHP from a tune alone. 453BHP was with both lower pulley and upper pulley (upper was 62mm-60.5mm which will add about 0.75lbs of boost, roughly 5-10BHP.) So with just the crank pulley you're probably around 445BHP.

Really, based on Lance's feedback I think if you are fitting the lower pulley to a V6, the upper pulley is... not a waste but perhaps not really worthwhile. The V6 already has a smaller pulley (62mm) than the V8 (65mm) and the boost level he is running with both pulleys does leave the car with a much more sensitive throttle. So for practicality and cost and general drive-ability I would say if you add something to the V6 do the crank pulley leave the charger pulley out.

As above, you can, but the lower pulley is really the low hanging fruit here.

 

Were I to do it again, I would not go with the upper pulley. Even though torque might come on sooner, I start losing boost and power over 6500 rpm because of the efficiency loss. Recommended max on the TVS R1320 is 18000rpm. The lower pulley alone gets you right there.

 

I hate to rob the thread a little but Lance where did you get your Eurotoys pulley from? Did you get it directly from Eurotoys? I was hoping to find a black friday deal on the lower pulley but on the Eurotoys website there $799 which seems a little pricey.

 

Yes, I got it from Eurotoys. The pulley is black anodized aluminum, is well made and comes with a belt and conversion idler to convert from a 2-sided grooved belt to a single sided so that the right size belt can be applied (not available in the right size as a double sided belt).

 

Gotcha. Thanks Lance!!!

 

Does changing the crank pulley cause any changes to accessories and what is the max safe boost and crank/pulley combo for the V8?

 

1. No. There are no accessories driven by the SC belt.
2. To determine the mast radical pulley combo, someone needs to contact Eaton to determine what the maximum recommended speed is on the TVS R1900 supercharger. It is probably higher than the 18,000 rpm specified for the TVS R1320 on the V6. That said, the engine can handle 20 psi of boost.

 

Wow 20PSI would be quite a jump from 11.2, I'll have to see what the maximum is. Interesting to see how much power it would make but the coiling would be a challenge.

That's a lot of airflow! This always happens each time I say I'm keeping it stock. I just need more passing power LOL

Time for some research
